Astronomers discover 83 supermassive black holes 13 billion light-years away

Washington, Mar 15: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor at Princeton University in the US.

“Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models,” Strauss said in a statement.

This finding, published in The Astrophysical Journal, increases the number of black holes known at that epoch  considerably, and reveals, for the first time, how common they are early in the universe’s history.

In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar.” Previous studies have been sensitive only to the very rare, most luminous quasars, and thus the most massive black holes.

The new discoveries probe the population of fainter quasars, powered by black holes with masses comparable to most black holes seen in the present-day universe.

The team used data taken with “Hyper Suprime-Cam” (HSC) instrument, mounted on the Subaru Telescope of the National Astronomical Observatory of Japan, which is located on the summit of Maunakea in Hawaii.

The researchers selected distant quasar candidates from the sensitive HSC survey data.

They then carried out an intensive observational campaign to obtain spectra of those candidates, using three telescopes: the Subaru Telescope; the Gran Telescopio Canarias on the island of La Palma in the Canaries, Spain; and the Gemini South Telescope in Chile.

The survey revealed 83 previously unknown very distant quasars.

Chouhan made the announcement in a series of tweets.

“My dear countrymen, I had symptoms of COVID-19 and after the test, my report has come back positive. I appeal to all my colleagues that whoever came in contact with me, must get their corona test done. And my close contacts should quarantine themselves,” Chouhan said in a tweet in Hindi.

“If COVID19 is treated on time, a person is completely cured. I have been reviewing the status of corona infection every evening since March 25. I will try to review corona situation through video conferencing as much as possible now,” he added.

The chief minister said the review meeting will now be held by home minister Narottam Mishra, urban development and administration minister Bhuppendra Singh, health education minister Vishvas Sarang and health minister Dr Prabhuram Choudhary in his absence.

“I will also continue to do everything possible to help control COVID19 in the state during treatment,” he said.

One of Chouhan’s ministerial colleagues tested positive for Covid-19 late on July 22.

The chief minister along with the minister, the Bharatiya Janata Party’s state unit president VD Sharma and state unit general secretary (organisation) Suhas Bhagat had visited Lucknow in a government plane on July 21 to attend the funeral of MP governor Lalji Tandon who died away in the Uttar Pradesh capital, his hometown. during hospitalisation.

The minister is admitted to a private medical college’s teaching hospital in Bhopal.

Mumbai, Mar 4: BJP leader Devendra Fadnavis on Tuesday said Maharashtra Chief Minister Uddhav Thackeray should not give "vague" replies on the 5 per cent Muslim quota issue and declare "with courage" that his government will not bring law granting reservation to the minority community.

Mr Fadnavis made the remark after Mr Thackeray, during a press conference earlier in the day, said he has not yet received the proposal regarding giving quota to Muslims and that the Shiv Sena-led government is yet to take any decision on it.

Mr Thackeray made the comments after Maharashtra Minority Affairs Minister Nawab Malik recently said in the legislative council that thestate government will provide 5 per cent quota to Muslims in education.

Mr Malik, an NCP leader, had also said the state government will ensure that a legislation to this effect is passed soon.

The NCP and the Congress, both proponents of Muslim quota, are constituents of the Sena-led Maha Vikas Aghadi government.

Asked about Mr Thackeray's remarks on the issue, Mr Fadnavis said instead of making comments at the press conference, the chief minister should make a statement in the legislature which is currently having its budget session.

The Leader of the Opposition in the assembly said that Mr Malik's opinion is the official position of the government as the minister had talked about giving quota in the council.

"So, instead of making vague comments in the press conference, the chief minister should say in the council that it is not his view (the one expressed by chief minister).

"The chief minister gave vague answers during the press conference, saying the proposal has not come to him. Your minister (Malik) only has said it," Mr Fadnavis told reporters outside the legislature building complex.

The BJP leader maintained there is no provision in the Constitution for religion-based reservation in government jobs or education.

"Say with courage that you will not give the quota, that the Constitution doesn't accept quota based on religion. Hence, we (the government) will not bring law granting quota," the former Chief Minister said.

Mr Fadnavis claimed that if given within the 50 per cent ceiling set by the Supreme Court, the Muslim quota will affect the existing reservation granted to OBCs.

"And if given outside it, it will affect Maratha quota," he added.

New Delhi, Feb 26: Calling the recent violence in Delhi as 'planned conspiracy', Sonia Gandhi on Wednesday demanded Union Home Minister Amit Shah's resignation over the clashes that left 20 people dead in two days.

"CWC (Congress Working Committee) believes Home Minister and Centre is responsible. The Home Minister should tender his resignation with immediate effect," the Congress party's interim chief told reporters here.

Violent clashes erupted between pro and anti-CAA groups in parts of northeast Delhi on Monday, leading to widespread vandalism and arson for over two days.

While many blamed police for inaction to control the mobs, Union Home Minister Amit Shah met the top brass of Delhi Police, Chief Minister Arvind Kejriwal, LG Anil Baijal and directed the officials to control the situation.

Gandhi blamed both the Central and the Delhi governments, saying the administration did not take adequate steps on time to curb violence in the national capital.

"Chief Minister Arvind Kejriwal and Center is equally responsible for not activating the administration to reach out to the people to maintain peace and harmony," Sonia added.

The death toll in the violence rose to 20 on Wednesday, according to GTB hospital authorities.

Government sources told ANI that the National Security Advisor (NSA) Ajit Doval has been given the charge of bringing normalcy in the capital.

Sources also said that Doval will brief Prime Minister Narendra Modi and the Cabinet about the prevailing situation.

The NSA last night visited Jaffrabad, Seelampur and other parts of northeast Delhi where he held talks with leaders of different communities.

Without naming any leader, the Congress interim president also targeted the leaders of the Bharatiya Janata Party for making inflammatory statements saying that "there is a conspiracy behind the violence, country also saw this during Delhi elections. Many BJP leaders made inciting comments creating an atmosphere of fear and hatred."
